When a sound wave passes from air into water do you expect the frequency wavelength to change?

The speed of the wave increases, the frequency remains constant and the wavelength increases. The angle of the wave also changes.

What is the frequency of a wave when one wave passes in 8 seconds?
Frequency is measured in Hertz (Hz), which is the number of wavelengths that pass in one second. Since one wavelength is passing every eight seconds, the frequency is 1/8 Hz.
If the speed of a wave doubles while the wavelength stays the same what happens to the frequency?
It will simply double.Wavelength = Velocity / Frequencyor in your caseVelocity = Frequency x wavelength+++Except that would demand unusual conditions.'Doubling of speed can only happen if the wave passes from its first medium to another of very different properties. Any given wave motion has a speed constant for any medium itself that is able to transmit it.'For sound, the speed is approximately 340m/s in air, 1500m/s in water (varying very slightly with the density of the air or water). This is irrespective of frequency hence irrespective of wavelength.'So for a single medium, as the speed cannot change (ignoring small changes due to density changes) the wavelength is always inversely proportional to frequency only.
If you make a wave in a rope so that a wave passes every second What is its frequency?
1 Hz
What is the slope of Passes through -2 2 and 2 -10?
(change in 'y') / (change in 'x') = (-12) / (4) = -3
What is the frequncy of the wave if it is 2 meter high 8 meters long and the time needed to complete one wave is 8 seconds?
If one wave completes, or passes a point, every 8 seconds, then the frequency is 1/8 Hz. = 0.125. The dimensions have nothing to do with the frequency.
When a wave passes from a less dense medium to a more dense medium what might change?
Velocity (speed and direction) Wavelength (frequency)
What happens to the speed wavelength and frequency when sound wave passes from cool air into warmer air?
the speed and wavelength increase but the frequency stays the same
Why wavelenth changes with speed of light?
Wavelength does not change with the speed of light, nor does the speed of light change for different wave lengths. Wavelength x frequency = c (the speed of light) always for any given medium through which it travels. Greater wavelength yields lower frequency, so the speed is always the same. Speed changes as light passes into different media transparent to light, but the change in speed has nothing to do with any change in frequency or wavelength. Those are related only to the nature of the material and the particular light energies it may pass or absorb. So white light passing through a red filter emerges red because the blue and green frequencies have been absorbed by the filtering material. That change in wavelength and frequency is not related to any change in speed within the filter.
When light passes through a prism how does the amount of bending of a light wave depend on the frequency of the light wave?
The question completely dissolves into nothingness when we recall that the frequency and wavelength of a wave are inextricably bound to each other. They don't change independently, and if you know one, then you know the other. So the "amount of bending" compared to frequency, and the "amount of bending" compared to wavelength, are necessarily identical.
What occurs when light passes from water into a flint glass?
Its speed decreases, its wavelength becomes smaller, and its frequency remains the same.
What happens to light as it passes through different mediums?
Its speed and wavelength change.
How are sound waves are affected by their frequency and the medium through which the sound wave passes?
The wavelength is equal to the local velocity of sound divided by the frequency, As with light, there can be refraction when sound passes from one medium to another with a different sound velocity.
How is the frequency of light affected when going between different media?
Once the light leaves the source, its frequency doesn't change, no matter what ittravels through or what kind of exciting adventure it encounters.But if it passes from one medium to another one with a different index ofrefraction, then the speed and wavelength change, and the direction of aray of light may change.
Does the frequency of a whales sound made underwater changes after being heard in air?
When a sound passes from one medium to another of different [non-zero] density, its speed and wavelength change, but its frequency doesn't. It doesn't matter what either medium is, or what source produced the sound.
Does light's Energy Decreases as it travels from air into water?
No the Energy of the light doesn't change when it passes through rarer to denser medium. Only Wavelength changes which cause change in its direction. Since Frequency is directly proportional to the Energy and frequency is constant during refraction therefore the energy also remain constant.
How is the energy of a photon related to its frequency and wavelength?
wavelength : wavelength is the distance from crest of one wave to the crest of next frequency : the number of waves that passes a given point in one second energy : the amplitude or intensity of a wave energy and frequency is directly proportional to each other when energy is high frequency is also high wavelength and frequency or energy is inversly proportional to each other when wavelength is high frequency or energy is low
A floating object oscillates up and down 2 complete cycles in 1 second as a water wave of wavelength 5 m passes by The speed of the wave is?
Just use the relationship: speed (of the wave) = frequency x wavelength. If the frequency is in hertz (cycles/second), and the wavelength in meters, then of course the speed will be in meters/second.
